Abstract

Objectives. Most adenocarcinomas of the prostate with a Gleason score greater than 8 at radical prostatectomy have extraprostatic extension and a high risk of progression. With prostate-specific antigen screening, we have seen some cases of earlier detected, organ-confined, high-grade adenocarcinoma. Few data are available as to the likelihood of cure in these cases. Methods. We reviewed 27 cases of pathologically organ-confined adenocarcinoma with a prostatectomy Gleason score of 8 to 10. To exclude cases with a significant proportion of Gleason pattern 3, we excluded cases of Gleason score 3+5=8 and Gleason score 5+3=8. All cases of Gleason score 8 at radical prostatectomy were Gleason score 4+4. The prognostic value of the clinical parameters (clinical stage, serum prostate-specific antigen level, age) and pathologic factors (biopsy Gleason score, radical prostatectomy Gleason score, prostatectomy tumor volume) were tested to predict postoperative progression. Results. The mean age at diagnosis was 59.7 years (range 46 to 69) with preoperative serum prostate-specific antigen levels ranging from 1.4 to 28 ng/mL (mean 7.8). All tumors were classified as pathologic Stage T2N0Mx. Fifteen patients (55.6%) had a Gleason score of 8, 11 patients (40.7%) had a Gleason score of 9, and 1 had a Gleason score of 10 (3.7%). Tumor volumes ranged from 0.02 to 1.44 cm3 (mean 0.56). Follow-up information was available for all men. The mean follow-up for those without progression was 30.6 months (range 7 to 73) and for those with progression was 23.6 months (range 9 to 44). The 33-month actuarial risk of progression was 32%, with 10 men developing progression during the study. None of the preoperative or postoperative variables predicted progression. Conclusions. Even when high-grade tumor is organ confined, it is associated with a relatively unfavorable short-term outcome that is not predictable on the basis of either preoperative clinicopathologic data or postoperative pathologic information obtained from the radical prostatectomy specimen.
